certain new and useful improvements in Fhonographic-ltecordatlbum Signatures, of which the following is a specification.

My improvements relate to the type of duplex envelop signatures set forth in my' concurrent application No. 304,476, filed June 16, 1919, for the containing and storage of phonographic disk records in va conveniently accessible manner,rny present invention consisting in the specific construction and arrangement of parts herein described and claimed, and a distinctive feature thereof being the method of forming the-duplex signature of envelops consisting of independent blanks folded and united into an integral. structure having a medial conjunctive spinal-hinge section by means of which each envelop reinforces the other, and the signature, considered as va whole, is

adapted for securement to the back or cover block of an album in the manner setw forth in the aforesaid concurrent application.

lin the accompanying drawings,

Figure 1, is a view of the inner face of the blank from which is formed what may be designated for convenience of description as the left hand envelop of the duplex signature;

Fig. 2, is a like view of the blank from `which is formed the other or right hand envelop of the signature;

Fig. 3, is a view ofthe left hand envelop formed ready for attachment to the right hand envelop;

Fig. dais a view of the right hand envelop formed ready for rattachment to the left hand envelop;

Fig. 5, is a view of the twoenvelops articularly attached and constituting the duplea signature;

Fig. 6', is a sectional detail upon an enlarged scale, and necessarily exaggerated'as to thicknesses, etc., illustrating the conjunctive structure of the signature; Fig. i?, is a diagrammatic projection, on the dat, of the parts shown in Fig. 6;

Fig. 8, is a sectional detail showing the spine of my duplex signature attached to an album back block.

duplex signature is designed to be se by means ofstaple tongues or equivalent'mechanical expedients driven through. its spine s, substantially as set forth in my'concurrent application hereinbefore' referred to, or as indicated by way of eXemplification in F ig. 8, ofthe accompanying drawings.

'llie envelop blanks d, and B, are duplicates of each other except that-in the formation of the duplex signature they are reversed longitudinally as related to each other, so that in reality the same form ofv blank is available' for the formation of either record pocket or envelop. Nevertheless it will facilitate understanding offthe construction involved if they are considered and described separately as well as jointly. Thus A, represents the blank used for the formation of what may be designated as thev Aleft hand envelop, and B, that used for the formation -of the right hand envelop, as hereinbefore intimated.

"lhe blank A, is formed with the usual sight openings a, and upper edge finger spaces a', and a2; and with a bottom flap a, foldable on the scored line am. lt is also formed with, the medial transverse scored line a3, which constitutes the outer or free edge of the envelop when the blank is folded, as well as with the other (parallel) transverse score lines at, a, a7, and as. scored line at, marks the limit of attachment margin a5, at that end of the blank 'while the scored line a, in like mannermarks the limit of marginal attachment at the otherend of the blank,-the three. lines a3, at, and

a, prescribing the width -of pocket. The y,

is then folded over and attached by suitable means-'to the edge am, of the opposite side of the pocket thereby forming and sealing the bottom of the latter. ln this condition, represented in Fig. 3, the left hand blank A, is

ready for attachment to the right hand blank BQ 'llhe latter, like unto blank A, is formed with the usual sight openings a, and upper edge finger spaces nl, and'b2; and with the bottom flap` b, foldable upon the scored` The titi

irav

line b1". It is also formed with the medial transverse scored line b3, which coincides with the outer or free edge of this envelop when the blank is folded, as well as with vother parallel transverse score'liries b4, Z1,

57, and bs. The scored line b4, marks the `limitfof attachment margin b5, at that end of the blank, while the scored line b, in

-sented in Fig. 4, t e rst fold is made on the medial line b3, and the margin b5, is adhesively attached to the corresponding space between the lines b, and bl, leaving the margin b9, withthe spine space s, protuberant beyond :the line bl. The flap b, is then folded overy andadhesively attached to the edge 512,*'of the opposite side of the pocket, therebyv'fo'rmin'g and sealing the bottom of the latter. In this condition, as represented in Fig".y 4, the right hand blank B, is ready blank A.

To permanently incorporate the two indehr pendently complete envelops thus formed into a unitary structure they are adhesively attached to each other between the line a4, and a, of the blank A, and the corres )onding line b, and edge b9, of the blank resulting in the duplex signature shown in Fig. 5.

This conjunctive structure of parts is illustrated roughly in Fig. 6, presuming that due allowance is made for the unavoidable exaggeration of thickness of material; it being understood that the blanks are made of relatively thin but tou h, tenacious, flexible material, such as anila paper or the equivalent thereof. Thus by reference to this Fig. 6, as well as to Fig. 7., it will be seen that the spine s, is two ply, while the A Kadjacent parts are three ply. That is to say, the overlap of the parts of the blank A, between lines as, and edge a, and the corresponding overlap of the parts of the blank B, between the line bs, and the edge b, afford an additional thickness or ply of material, on either side of the spine 8,-the object of which is not only to strengthen the conjunctivefmedial spinal hinge section of the duplex signature as a whole, and prescribe the lines of envelop articulation t0 coincide mainly with the edges a", and b, but also to use the latter' as a means for reinforcing the inner edges of the pockets as prescribed by the coincidental lines a, and

forfattachment to the left hands af, and b, and b, respectively, so as to reslst the tendency offa record disk to strain and pry apart the inner walls of the pockets Yalong these lines, as will be understood by I record disks, while the bottoms of the pockets are sealed by the iaps a", b, in a like manner. In other words, the inner edges of the pockets are prescribed, not by a fold ofmaterial, like the other edges thereof, but simply by the adhesion of parts along the lines a4, a6, and b4, 1), and for this reason particularly I reinforce these lines by means of the marginal edges a, b, of both blanks. These edges also, as before intimated, tend to limit and prescribe the line of flexure or articulation of the pockets or envelops as related to theoconjunctive structure of the duplex signature.

It may be noted that the extension of each blank beyond the pocket lines constitutes a spinal hinge section of which the spine s, is the central portion; and that these extensions are on the right of the left hand blank and on the left of the right hand blank so that when that of the right hand envelop is superposed upon and adhesively attached to that of the `left hand envelop we haver the correlation of extension parts illustrated in Figs. 6 and 7.

Vhat I claim as my invention and desire to secure byLetters Patent is,

1. A` duplex signature for phonographic record albums of the character designated, consisting of independently formed record envelops, each having a spinal hinge extension overlapping and adhesively secured to that .of the other, for the purpose described.

2. A duplex signature for phonographic record albums of the character designated, consisting of independently formed record envelops, each having a spinal hinge extension overlapping and adhesively secured to that of the other, each of said extensions being formed with a medial spine portion and with an edge fiap portion beyond the spine portion so that the conjunctive struce ture is three ply between said spine and the' A inner edge lines of the pockets, for the pur Witnesses:
